Running into OSCAR in Black Ops 7 Zombies can ruin a good run fast. You are cruising through the early rounds, guns feel decent, perks are stacked, then this walking bunker shows up and everything slows down. His health is wild, sure, but it is those floating drones and the shield they give him that really tilt people. You think you are doing damage, then realise nothing is sticking and you are just dumping ammo for no reason. If that sounds familiar, you are not alone, and plenty of players try to brute force it instead of treating OSCAR like a real boss encounter you have to plan for in the same way you plan for a sweaty lobby or a tricky CoD BO7 Bot Lobby challenge.

Getting Set Up Properly

The big thing people mess up is trying to fight OSCAR with a base gun and no plan. If your weapon is not Pack-a-Punched by the time he starts spawning, you are already on the back foot. Get that PaP done early, even if it means delaying a perk or two. You also want something that can control a crowd while you focus him, like equipment that slows or funnels zombies so they do not wrap around you while you are staring at his drones. In squads, one player peeling the horde off OSCAR makes life way easier. If you are solo, it turns into constant kiting and repositioning, never staying in one spot long enough for the zombies to box you in.

Using The Sunlight Beam Trap

The cleanest way to delete OSCAR is the Sunlight Beam in the Pack-a-Punch room. Once power is on, head in there and look for those steaming valves. Shoot them until the old mechanism kicks into life. Then use the telescope by the organ to line up the beam; it feels a bit like you have wandered into a puzzle room rather than a zombie map, but it is worth taking a minute to line it up. When OSCAR shows up, drag him onto the platform between the organ and the PaP machine. If you keep him there long enough, the beam hits and he just melts. No mags emptied, no panicked reloads, just a big boss gone in a flash while you save your ammo for the next wave.

Rocket Trap And Cryo Setup

When you are not near the PaP area, the museum Rocket Trap is the backup play. This one takes a bit more effort, because you need the Cryofreeze ammo mod ready to go. You have to track down those purple Aetherium crystals, hit them with Cryo, and grab the shards that drop. Once that is sorted, drag OSCAR behind the rocket, trigger the trap and let the blast chew through his health. It is not as instant as the Sunlight Beam, and the setup can feel slow in the middle of a run, but it is solid when you are already rotating through that side of the map and do not want to double back to the Luminarium or PaP area.

Luminarium Overcharge And Reward

The high-effort route is the Luminarium Overcharge, which ties into the Easter egg path. You are running around picking up a damaged drone, shooting the hood of the truck everyone calls Ol’ Tessie with a Pack-a-Punched gun to knock loose a car battery, then grabbing wires from that glitched-out lamppost that never looks quite right. Plug all that into the Luminarium and you can overcharge the whole thing. When you kite OSCAR into the zone, he goes down and drops the LGM-1 Wonder Weapon, so it feels way more like a proper boss payoff than just another mini-event. If you are the type who likes squeezing extra value out of every spawn and every objective, this method turns a headache into a chance to gear up harder for later rounds and for tougher modes like a stacked CoD BO7 Bot Lobby buy session.
